Abstract

An electronic device with automatic anti-drop function includes a main body and an automatic anti-drop device. The automatic anti-drop device includes an anti-drop assembly, a power, a controller and a sensing device. The anti-drop assembly includes an electromagnetic device, an elastic member and a buffer block. The electromagnetic device is connected to the power electronically. The buffer block is connected to the main body by the electromagnetic device and the elastic member. In an initial state, the power supplies for the electromagnetic device, the buffer block is adsorbed on the main body, and the elastic member is in a compression state. When the sensing device detects that the electronic device falls, the controller controls the power to stop supplying for the electromagnetic device, an elastically recovery force of the elastic member pushes the buffer block away from the electronic device, which can protect the electronic device when the electronic device falls.
